Hello!

I read docs.. threads with keyword 'multicast' here... no answer.

With ZfD 4.0.x (more patchlevels), now with ZfD 6.5.SP1.. NW 6.5.SP3;

Unicast imaging working fine.

Multicast session from workstation master working, but this is not solution.

Multicast with server - session starting..

(1) manually from IMGSERV and ZEN-Linux commandline, or

(2) automatically via rule ..

- THEN ZEN-Linux img wrote "Waiting for session master to start" and
IMGSERV list this session (multicast session panel), BUT with 0/x clients..
until timeout ('Update requests' and 'Images sent' counters increased).

Switches and routers are not issue, because finally test is reduced to one
workstation on cross TP patch cable connected to server.

Server has two network interfaces. pdhcp.ini is configured for 'lab
network' only, only for imaged workstation. I try 'load imgserv
i:<lab-ip>', with strange results (lost auto start from PXE), but no
pozitive effect.

PIM is loaded.

I try IMGSERV -debug .. finaly found this section:

All data appears correct, but 'no clients' message. (MCA is acronym for
some multicast function?)

In this LOG is not reported multicast IP for this session, from IMGSERV
point of view.
